1. Remove valve covers. See «VALVE COVERS»(ref-22905-S26337586552001011500000). Remove front cover. See «FRONT COVER»(ref-22905-S24719314042001011500000). Remove crankshaft position sensor pulse wheel from crankshaft.
2. Rotate crankshaft until No. 1 piston is at TDC. This positions crankshaft keyway 45 degrees from vertical position. (Scheme 10) Camshaft keyways will point toward crankshaft. CAUTION: Mark component location for reassembly reference. Components must be installed in original locations.
3. Install Camshaft Positioner (T92P-6256-A) on flat area near rear of camshaft. (Scheme 13) Remove retaining bolts, right chain tensioner, right tensioner arm and right chain guide. (Scheme 14)
4. Remove right timing chain and crankshaft sprocket. Note direction of sprocket for installation reference. If necessary for clearance, remove retaining bolt, washer, camshaft sprocket and spacer. CAUTION: DO NOT rotate engine with timing chain(s) removed. Damage to valve/piston may result.
5. Remove retaining bolts, left chain tensioner, left tensioner arm and left chain guide. (Scheme 14) Remove left timing chain and crankshaft sprocket. Note direction of sprocket for installation reference. If necessary for clearance, remove retaining bolt, washer, camshaft sprocket and spacer.

Inspection

Inspect components for damage. Inspect friction surfaces on tensioner arms and chain guides for wear. Replace components if necessary. If tensioner arms or guides are worn or damaged, remove and clean oil pan. Also, replace oil pump screen cover and tube.

Installation

1. Install spacers, camshaft sprockets and retaining bolts. Ensure components are installed in original locations. Tighten bolts to specification. See «TORQUE SPECIFICATIONS»(ref-22905-S08863470302001011500000).
2. Install Camshaft Positioner (T92P-6256-A) on flat areas of camshaft if not previously installed. (Scheme 13) CAUTION: Install crankshaft sprocket halves with hubs facing each other. (Scheme 11)
3. Install crankshaft sprocket for left timing chain. If copper links are not visible on timing chain, fold timing chain in half and mark each end link for timing purposes. (Scheme 11) These links will be referred to as copper links when installing.
4. Ensure No. 1 piston is at TDC. This positions crankshaft key-way 45 degrees from vertical position. see scheme 6 Crankshaft keyway will point toward camshaft.
5. Install left timing chain on camshaft and crankshaft sprockets so copper link aligns with timing mark on sprockets. (Scheme 11) Install crankshaft sprocket for right timing chain. Ensure sprocket is properly installed. (Scheme 12)
6. Install right timing chain on camshaft and crankshaft sprockets so Copper link aligns with timing mark on sprockets. (Scheme 11) Install Crankshaft Positioner (T93P-6256-A), to prevent crankshaft movement. Lubricate tensioner arms with engine oil. Install tensioner arms. Install chain guides.
7. Chain tensioners must be bled down so tensioner plunger is compressed in housing before installing. Place chain tensioner in soft-jawed vise. Using small pick, hold ratchet lock mechanism away from ratchet stem. (Scheme 12) Slowly close vise to depress tensioner plunger.
8. When tensioner plunger is compressed in housing, continue to hold ratchet lock mechanism and install lock pin in hole on tensioner housing. Ensure ratchet stem is even with tensioner housing before installing lock pin. (Scheme 12)
9. Using a "C" clamp or suitable tool, remove all slack from the timing chain by applying pressure to the tensioner arm. While holding pressure on arm, install both chain tensioners and retaining bolts on cylinder block. Tighten retaining bolts to specification. See «TORQUE SPECIFICATIONS»(ref-22905-S08863470302001011500000)..
10. Remove lock pins from both chain tensioners. Ensure all timing marks align. (Scheme 10) To check accuracy of valve timing, remove No. 1 spark plug. Using a dial indicator, check for maximum intake valve lift. Maximum intake valve lift should occur at 114 degrees after TDC.
11. To install remaining components, reverse removal procedure. Before installing valve cover, apply silicone sealant at front cover-to-cylinder block areas.
12. When installing fuel lines, fit new fuel resistant "O" rings (Brown) on fuel lines. Lightly coat "O" rings with clean engine oil before installing. Clean fittings, and replace garter spring (if necessary).

Removal

1. Remove valve covers. See «VALVE COVERS»(ref-22905-S26337586552001011500000) . Rotate crankshaft until piston in cylinder to be serviced is at bottom of its stroke and camshaft lobe is at base circle.
2. Install Valve Spring Spacer (T91P-6565-AH) between valve spring coils to prevent valve stem oil seal damage. Using Valve Spring Compressor (T91P-6565-A), compress valve spring. Remove camshaft follower and lash adjuster.

Inspect components for damage. Measure lash adjuster O.D. and oil clearance. Replace components if damaged or measurements are not within specification. See VALVE LASH ADJUSTER table under ENGINE SPECIFICATIONS.

1. To install, reverse removal procedure. Coat components with engine oil before installing. Before installing valve cover, apply silicone sealant at front cover-to-cylinder block areas.
2. When installing fuel lines, fit new fuel resistant "O" rings (Brown) on fuel lines. Lightly coat "O" rings with clean engine oil before installing. Clean fittings, and replace garter spring (if necessary).

Remove the camshaft followers and the lash adjusters. See CAMSHAFT FOLLOWER & LASH ADJUSTER. Remove the timing chains. Refer to TIMING CHAINS. Remove camshaft cap bolts in reverse order of tightening sequence. (Scheme 16) Tap camshaft caps in designated areas to remove camshaft caps. (Scheme 15) Remove camshaft caps and camshaft.

Scheme 15

Measure camshaft bore I.D., journal O.D., oil clearance and lobe lift. Replace camshaft if measurements are not within specification. See See CAMSHAFT table under ENGINE SPECIFICATIONS.

1. Coat components with engine oil, and install components. Install all bolts for both camshaft caps, and tighten them finger tight. Tighten bolts to 72-106 INCH lbs. (8-12 N.m) in sequence. (Scheme 16) Loosen all bolts 2 turns. Retighten bolts to 72-106 INCH lbs. (8-12 N.m) in sequence. Repeat procedure for each camshaft. CAUTION: Ensure proper procedure is used when installing timing chains to prevent engine damage. See «TIMING CHAINS»(ref-22905-S11526590282001011500000).
2. Ensure camshaft end play is within specification. See See «CAMSHAFT»(ref-22905-S18190450192001011500000) table under ENGINE SPECIFICATIONS. To install remaining components, reverse removal procedure. Tighten all bolts to specification. See «TORQUE SPECIFICATIONS»(ref-22905-S08863470302001011500000).
